Description

  The present invention relates to an image capturing apparatus and method thereof, and more particularly to an image capturing apparatus and method for automatically setting the resolution of an image stored according to the type of recording medium selected by a user.

  Generally, a digital still camera (DSC) converts an image incident through a lens into a digital signal and stores it in a recording medium such as a hard disk or a memory card. In other words, a captured image can be stored in the recording medium without being recorded on a film or the like, and a digital image can be directly input to a computer without using a scanner.

  Such a DSC is highly compatible with a PC, is easy to edit and modify, and can transmit images taken in conjunction with an external computer. The DSC has a structure similar to that of a general camera, so it is easy to carry. That is, the DSC includes a lens device, a memory device, a signal modulation device, a display device, and the like.

  By the way, such DSC is mainly used for shooting a stop video for reasons such as the capacity of a recording medium for recording the video. That is, although it has a function that can shoot some moving images, it is practically impossible to shoot for a long time. In particular, since there is no device for recording and playing back sound together when shooting and playing back moving images, it is practically inappropriate for shooting and storing and playing back moving images.

  In order to satisfy these points, recording / reproducing apparatuses for recording and reproducing images and sounds of a subject photographed on a recording medium such as a tape, for example, a camcorder, that is, a digital video camera (DVC) are widely spread. Has been.

  The DVC includes a lens device, a signal conversion device, a deck device for recording / reproducing captured images, a display device, and the like. Such DVC mainly uses a cassette tape as a recording medium, and records a moving image shot by mounting the cassette tape on a deck device. Moreover, DVC is equipped with the microphone apparatus and the speaker apparatus, and can image | photograph 1 hour or more on the mounted cassette tape.

  Such a DVC also has a function of capturing a stop image. However, since the image quality is lowered as compared with the DSC described above, it is mainly used for capturing a moving image. In addition, since the DVC has a variety of functions and is configured more complicatedly than the DSC, the size is generally large and expensive.

  By the way, as described above, in order to utilize each function of DSC and DVC, it is necessary to purchase all two products. Therefore, consumers were economically burdened. Also. Since each feature is unique even after purchase, there is a problem that it is inconvenient to carry when all the functions of the two products are required.

  In order to solve such problems, a DSC integrated DVC in which a DSC and a DVC are integrated into one case has been developed, and this is called a digital camera / camcorder or a duocam (DUOCAM).

  The duo cam is a recording medium for storing captured images, using a memory card and a magnetic tape, and a user can select one of the two to record the captured image. A memory card is small in size and has an advantage that it can be directly connected to a PC and easily transmit data. However, there is a disadvantage that the storage capacity is small, and a magnetic tape has the disadvantages of a memory card. In a memory card having a small storage capacity, it is preferable to store a low-resolution video as low-capacity data in terms of efficient use of the storage space. On the other hand, since magnetic tape has a large storage capacity, it does not matter if it is stored as a high-resolution video.

  However, in the conventional duo cam, the resolution of the video stored by the recording medium selected by the user is not automatically set to be different, so the user must set the resolution directly depending on the recording medium selected by the user. There was an inconvenience that would not have been.

  Referring to FIG. 1, the display unit 150 includes a viewfinder 151 that is provided on the main body 100 and displays a captured image, and an LCD panel 152 that is formed on the main body 100.

  The stop video imaged by the DSC is stored in the removable IC memory card 121. The user can select the resolution of the stop video to be stored using a DSC resolution selection unit (not shown). When the resolution is high, the data capacity is large and the number of photos that can be stored is small. When the resolution is low, the data capacity is small and the number of photos that can be stored is large. For example, if the storage capacity of the removable IC memory card 121 is 32 MB, about 52 photos can be stored if the resolution is 2272 × 1704, and about 360 if the resolution is 640 × 480.

That is, the recording medium selection switch 131 outputs a memory recording mode signal or a tape recording mode signal to the main control unit 141 according to the user's selection.

  On the other hand, the user can select a recording medium with a recording medium setting unit (not shown). The recording medium setting unit includes a key input unit 130, a display character generation unit 155, and a display unit 150, and the function of each component is the same as that described in the DSC resolution selection unit.

  5A to 5B are diagrams for explaining a process of setting a recording medium using a menu screen.

  As shown in FIG. 5A, when the photographing apparatus is operated in the DVC operation mode, when the user presses the menu display key, a DVC menu screen is displayed on the display unit, and the cursor '1. When the selection key placed on the “recording medium” is pressed, “1. ‘(1) Memory’ and ‘(2) Magnetic tape’, which are subordinate menus of the recording medium, are displayed.

  As shown in FIG. 5B, when the user subsequently uses the direction key to position the cursor on '(2) magnetic tape' and presses the selection key, the main controller 141 causes the captured moving image to be magnetic. The storage path is set so as to be stored on the tape 122.

  The controller 140 includes a main controller 141 and a DSC controller 142. The main controller 141 determines which of the DSC operation mode and the DVC operation mode is the current operation mode based on the operation mode signal received from the mode selection switch unit 300.

  If it is determined that the mode is the DSC operation mode, the main control unit 141 controls the DSC control unit 142, and the DSC control unit 142 controls the DSC lens driving unit 231 and the DSC signal processing block 111. . Therefore, the optical image formed through the DSC lens unit 211 is photoelectrically converted into an electrical signal by the DSC CCD 221, and the converted signal is converted into digital stop video data by the DSC signal processing block 111.

  The main control unit 141 changes the resolution of the digital stop video data output based on the signal received from the DSC resolution selection unit. That is, the main control unit 141 adjusts the DSC resolution selection switch 113 so that the digital stop video data output from the DSC signal processing block 111 is transmitted to any one of the third to sixth resolution conversion units. To.

  The digital stop video data is transmitted to the fifth resolution conversion unit 175 to 2272 × 1704 resolution when transmitted to the third resolution conversion unit 173, and to 2272 × 1504 resolution when transmitted to the fourth resolution conversion unit 174, respectively. Then, it is converted to 1600 × 1200 resolution, and when it is transmitted to the sixth resolution conversion unit 176, it is converted to 640 × 480 resolution. The converted data is compressed by the JPEG compression unit 181 with JPEG format data. The main control unit 141 adjusts the storage data selection switch 120 so that the JPEG format data output from the JPEG compression unit 181 is stored in the removable IC memory card 121.

  On the other hand, if the DVC operation mode is determined, the main control unit 141 controls the DVC lens driving unit 232 and the DVC signal processing block 112, and an optical image formed through the DVC lens unit 212 is output by the DVCCCD 222. The DVC signal processing block 112 converts the converted signal into digital moving image data by photoelectric conversion into an electrical signal.

  The main control unit 141 determines which recording mode is the current recording mode among the memory recording mode and the tape recording mode based on the recording mode signal received from the recording medium switch 131 or the recording medium setting unit (not shown). Determine whether.

  If it is determined that the memory recording mode is selected, the main control unit 141 adjusts the DVC resolution selection switch 114 and transmits the digital moving image data output from the DVC signal processing block 112 to the first resolution conversion unit 171. To be controlled. The first resolution conversion unit 171 converts the digital moving image data to 320 × 240 resolution. The data output from the first resolution conversion unit 171 is compressed by the MPEG compression unit 182 with the data in the MPEG format. The main control unit 141 adjusts the storage data selection switch 120 to store the MPEG format data in the removable IC memory card 121.

  When it is determined that the recording mode is the tape recording mode, the main control unit 141 adjusts the DVC resolution selection switch 114 and transmits the digital moving image data output from the DVC signal processing block 112 to the second resolution conversion unit 172. To be controlled. The second resolution conversion unit 172 converts the digital moving image data to 720 × 480 resolution. The data output from the second resolution conversion unit 172 is compressed with DV format data by the DV compression unit 183 and is finally stored on the magnetic tape 122 through the VCR deck 124.

  The mode selection switch unit 300 is installed to operate in conjunction with the composite camera unit 200, and outputs an operation mode signal corresponding to the rotation angle of the composite camera unit 200 to the main control unit 141. 141 receives the operation mode signal and determines the current operation mode.

  As shown in FIG. 3A, when the DSC lens unit 211 and the DSCCCD 221 are located within a 45 degree angle range with respect to the left side of X, the mode selection switch unit 300 controls the DSC operation mode signal as a main control. The control unit 140 operates the DSC unit 201 and turns off the DVC unit 202.

  On the other hand, as shown in FIG. 3E, when the DVC lens unit 212 and the DVCCD 222 are positioned within a 45 degree angle range with respect to the left side of X, the mode selection switch unit 300 outputs a DVC operation mode signal.

The connection terminal 230 provided in the composite camera unit 200 may be configured to be connected to any one of the 164. Therefore, the connection terminal 230 is in contact with any one of the first to fourth connection patterns 161 to 164 according to the rotation angle of the composite camera unit 200 with respect to the main body 100. Here, the first connection pattern 161 is connected to the first port of the main controller 141, the second connection pattern 162 is connected to the second port of the main controller 141, and the third and fourth connection patterns 163 and 164 are It is not connected to the port of the main control unit 141.

  FIG. 9 is a diagram illustrating a state in which no camera unit is selected by the changeover switch illustrated in FIG. 8. In this case, as shown in FIG. 9, when the connection terminal 230 is in contact with the third connection pattern 163, that is, the rotation angle of the composite camera unit 200 is in the third range (the connection terminal 230 is located above the Y axis). If the angle is within the range of 45 degrees on the left and right, the operation mode signal is not output to the port of the main control unit 141. The same applies to the case where the connection terminal 230 is in contact with the fourth connection pattern 164. Therefore, when the operation mode signal is not received, the control unit 140 turns off the camera unit in operation, so that the DSC unit 201 and the DVC unit 202 do not operate.

  At this time, assuming that the first to fourth connection patterns 161 to 164 are formed at an interval of 90 degrees, the DSC unit 201 is positioned when the connection terminal 230 is positioned at an angle of 45 degrees above and below the left side of the X axis. When the right side of the X axis is positioned at an angle of 45 degrees up and down with respect to the X axis, the DVC unit 202 operates, and is positioned at an angle of 45 degrees to the left and right with respect to the upper side of the Y axis, or If it is located on an angle of 45 degrees, no camera unit is activated. As described above, the reason that all the camera units are turned off at an angle of 45 degrees to the left and right with respect to the Y axis is that the user sets the zoom function and the DSC and DVC lens units 211 and 212 are combined camera units. This is to prevent the lens units 221 and 222 from colliding with the main body 100 when the composite camera unit 200 is rotated in a state of protruding to the outside of the unit 200.

  FIG. 10 is a diagram for explaining another example of the mode selection switch unit 300 of FIG. Referring to FIG. 10, a mode switch unit 310 is formed on a surface where the composite camera unit 200 contacts the main body 100, and a DSC mode switch 311 and a DVC mode switch 312 are formed in the mode switch unit 310. The DSC mode switch 311 is connected to the first port of the main controller 141, and the DVC mode switch 312 is connected to the second port of the main controller 141. When the composite camera unit 200 rotates with respect to the main body, the mode switch unit 310, the DSC mode switch 311 and the DVC mode switch 312 formed in the composite camera unit 200 also rotate.

  The DSC mode switch 311 can rotate in the d1 and d2 ranges. When the DSC mode switch 311 is positioned in the d1 range (45 degrees to the left and right with respect to the lower side of the Y axis), the binary signal “1” that is the DSC operation mode signal for operating the DSC unit 201 is The binary signal “0” is output to the first port and the second port of the main control unit 141.

  On the other hand, the DVC mode switch 312 can rotate in the d3 and d4 ranges. When the DVC mode switch 312 is positioned in the d3 range (90 degrees on the left side with respect to the lower side of the Y axis), a binary signal “1” that is a DVC operation mode signal for operating the DVC unit 202 is output from the main control unit 141. The binary signal “0” is output to the second port and to the first port of the main control unit 141.

  FIG. 11 is a flowchart for explaining a photographing method according to the present invention. Referring to FIG. 11, the main control unit 141 determines an operation mode based on the operation mode signal received from the mode selection switch unit 300 (S500).

  If it is determined in step S500 that the DSC operation mode is set, the DSC CCD 221 photoelectrically converts an optical image formed through the DSC lens unit 211 with an electrical signal and transmits the converted image to the DSC signal processing block 111 (S511). The DSC signal processing block 111 converts the signal into digital stop video data (S513).

  The main control unit determines the resolution to be converted based on the signal received from the DSC resolution selection unit (S5151, S5153, S5155). The digital stop video data output from the DSC signal processing block 111 is converted into one of 2272 × 1704 resolution, 2272 × 1504 resolution, 1600 × 1200 resolution, and 640 × 480 resolution (S5171, S5173, S5175, S5177).

  The JPEG compression unit 181 compresses the converted data with JPEG format data (S518). The JPEG format data is stored in the removable IC memory card 121 (S519).

  On the other hand, if the DVC operation mode is determined in step S500, the DVCCCD 222 photoelectrically converts the optical image formed through the DVC lens unit 212 into an electrical signal, and transmits it to the DVC signal processing block 112 (S521). The DVC signal processing block 112 converts the signal into digital video data (S523).

  The main control unit 141 determines the recording mode based on the recording mode signal received from the recording medium selection switch 131 or the recording medium setting unit (S525).

  If it is determined in step S525 that the memory recording mode is selected, the digital moving image data output from the DVC signal processing block 112 is converted to 320 × 240 resolution (S5271). The converted data is compressed with MPEG format data by the MPEG compression unit 182 (S5281). Also, the MPEG format data is stored in the removable IC memory card 121 (S5291).

  If it is determined in step S525 that the recording mode is the tape recording mode, the digital moving image data output from the DVC signal processing block 112 is converted to 720 × 480 resolution (S5272). The converted data is compressed with DV format data by the DV compression unit 183 (S5282). The DV format data is stored on the magnetic tape through the VCR deck 124 (S5292).
